Abbott Ditch Improvements
Client: City of Alamogordo

Abbott Ditch Larkin Group NM provided design for paving of a large drainage channel in Alamogordo. This channel, which parallels Abbott Street, had eroded during past storms to the extent that Fourth Street was closed because the channel had eroded so that the south side of it was adjacent to and several feet below the north curb. The project consists of approximately 2,000 linear feet of concrete-lined channel, including required earthwork and connections to existing structures upstream and downstream. To maintain drainage of the surrounding areas several run-downs were provided to conduct stormwater from Fourth Street and from a neighborhood to the north into the channel without erosion. An existing maintenance ramp was connected to the channel floor by a short concrete ramp, to allow channel bottom access for maintenance.

Southwest Valley Flood Reduction Project Phase IIA – Pond 187 Outfall
Client: Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA)

This project is part of the South Valley Flood Damage Reduction Project. These elements provide for diversion of high flows from Isleta Drain to large detention ponds reducing flood level in the drain. Following the flood peak the water flows back to the drain to be discharged to the Rio Grande.

Isleta Diversion Pond 187A Excavation Project: Excavation of Pond 187A, rough grading of the Albuquerque Public Schools (APS) parking lot, rough grading of an APS soccer field, and installation of pipe railing and placement of aggregate base course on access roads.

Pond 187 Conveyance: Excavation of channel to convey flows from Pond 187A to Pond 187. Installation of 30-inch-diameter RCP and 72-inch-diameter RCP and construction of grated trash box at outlet of channel.

Pond 187 Outfall in La Fonda Drive – Construction: Construction of elliptical RCP from Pond 187 to Isleta Drain, relocation of waterline, and removal and replacement of pavement on La Fonda Drive.

Isleta Drain Diversion Structure: Construction of a large channel with vertical walls including an orifice wall for normal drain flows and a grated weir to divert flood flows from the Isleta Drain to Ponds 187A and 187.

CR D and CR L
Client: Curry County

These two roads in the northern part of Curry County were designed under our on-call contract. Both roads had suffered erosion during past heavy rainfall events. Since the roads were badly damaged in a very large storm in 2016, the County applied for and received Disaster Relief Funding from the State to reconstruct these roads.

CR L The project on Road D is one mile long and serves several large dairy farms, which produce a significant volume of heavy truck traffic. It has a relatively flat grade, and floods frequently under heavy rains. This project serves as the drainage route for several sections of farmland to the north and west. Therefore, during heavy rains the roadway carries large flows. Because there were no drives on the west side of the road and most of the drainage comes from west of the road, we elected to widen the west ditch and eliminate the east ditch. This way we could provide more waterway within the 40-foot-wide right-of-way.

Road L is also in the northern part of the County, but considerably west of Road D. It carries drainage from surrounding farms to Rainwater Draw. The section of the road contained in the project is crossed by Rainwater Draw, a large drainage channel that crosses northern Curry County. Unlike most of the County, the part of the project on each side of the draw has relatively steep slopes. These steeper slopes have added to the erosive effects of the runoff. To provide wider and slower flows in the ditches, we eliminated the western ditch from the road and designed an eight-foot flat bottomed ditch on the east side of the road. This ditch was lined with riprap for additional erosion control.

500,000-Gallon Water Storage Tank
Client: Village of Cloudcroft

Cloudcroft Water Tank Larkin Group NM designed and managed construction engineering of a 500,000-gallon finished water storage tank for the Village of Cloudcroft at their new water treatment facility. This project, funded with Colonias funds, was completed in the summer of 2015.

Water System Improvements
Client: Bluewater Acres Domestic Water Users Association

Water Tank Larkin Group NM was selected to review and update an existing Preliminary Engineering Report (PER) for the Association. After restudy, meetings, and some rewriting, we were able to gain USDA-RUS approval for a modified/updated PER. Our new alternative included the construction of a new storage facility, drilling and developing a new well, and various water main upgrades/replacements and installation, including construction of 3.5 miles of 8-inch pipeline. The improvements were "phased," to allow for funding and expenditures over a multi-year period. Final design was completed and approved by both NMED and RUS.

The Larkin modified design developed with the owner has been built. This includes a new tank with enough capacity for two days’ storage plus 60,000 gallons for fire flow. As part of our work for Bluewater DWUA, we coordinated the construction documents with the Bureau of Reclamation (BoR). We met with their staff and conformed our well specifications to their standards. Subsequently our documents were used to obtain additional funding, with BoR assistance, for the groundwater testing and well drilling.

La Union Area Drainage Master Plan
Client: Doña Ana County Flood Commission

Major Damage in La Union after Major Storm Larkin Group NM prepared a Master Drainage Plan for the historic town site of La Union. At La Union a number of medium-size arroyos combine to generate large flows through the community during intense rain events. This has caused significant flood damage in the past. However, at the public meetings, we found that the residents were concerned about damage and nuisance produced by relatively minor rain events. The flows from smaller events were generated mostly within the community. These flows caused erosion of the fine-grained soils and deposition of them in low areas. Therefore, the study concentrated on both types of flows to produce a plan to reduce peak flows and carry them safely through the community using large detention basins and outlet pipes or channels, and a plan to reduce damage from lesser rainfall events by using inverted crowned streets and infiltration basins to carry flows and encourage groundwater recharge.

Our recommendations were timely, because in the same week that we presented the study to the County Commission, the La Union area was struck by a large storm that produced very large flows in the upstream arroyos. This storm caused the failure of one of the existing upstream agricultural ponds, and the resulting flow caused serious flooding and erosion. Major damage occurred throughout the small community.

Access "A" / Don Julio Road at NM 528
Client: Village of Corrales

Access A / Don Julio Road at NM 528 Larkin Group NM prepared the plans and details for the development of a four-way intersection at Northern Boulevard and NM 528 in the City of Rio Rancho, providing for a new eastern "leg" (Access "A" / Don Julio Road) into the Village of Corrales. We prepared a full set of construction drawings including geometry, drainage and grading, and traffic signals and controls for this MAP-funded project. Larkin Group NM also prepared a series of property acquisition maps in order for the Village to obtain the necessary right-of-way.

Agency and Area-Wide Flood Control Maintenance Contract 2012-2013
Client: Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA)

Agency and Area-Wide Flood Control Maintenance A maintenance project to inspect and prioritize the extent of maintenance (repair points) type repairs for select reaches of the various AMAFCA/NMDOT/City of Albuquerque flood control structures / channels in the Albuquerque area. This project also included on-call assignments for the design and construction of emergency repairs.

Bear Canyon Arroyo Bicycle/Pedestrian Bridge over I-25
Client: City of Albuquerque

Bear Canyon Arroyo Bridge at I-25 Bear Canyon Arroyo Bridge at I-25 The goals of this project are several. First, it provides a commuter and recreational crossing of I-25. This with other current improvements will provide bicycle routes from the Foothills to trails along the North Diversion Channel and along the Bosque. The second major goal is to provide pedestrian access between businesses east and west of I-25. Finally, it is important that these facilities be available to persons with disabilities. The bridge was opened to the public in December of 2012.

This project received the Best 2013 Project - Best Small Project (under $10M) award from the Engineering News-Record (ENR).

Bear Canyon Arroyo Trail (from west of Arroyo del Oso Golf Course to Wyoming)
Client: City of Albuquerque

Bear Canyon Arroyo Trail The two-mile multi-use Bear Canyon Arroyo Trail begins at a connection to an existing bridge crossing the Bear Canyon Arroyo and extends east to Wyoming Boulevard adjacent to an arterial roadway and the Arroyo del Oso Golf Course. The 10-foot-wide asphalt-paved trail services both bicyclists and pedestrians. A 6-foot-wide jogging path surfaced with a combination of crusher fines and natural soil is provided along a 1.5-mile portion of the trail. The alignment and grade of the trail were carefully selected to take advantage of the existing adjacent trees and other golf course amenities. To align the trail with an existing trail east of Wyoming, the trail crosses the Bear Canyon Arroyo on the east side of the Arroyo del Oso Golf Course. The prefabricated bicycle/pedestrian bridge, with a span of about 148 feet, crosses an undeveloped portion of the arroyo at a skew of 45 degrees.

Sierra County Projects
Client: Sierra County Road Department

Sierra Vista Hospital Parking Lot Sierra Vista Hospital Site Improvements: This project was to prepare design of improvements to the site in preparation for additions to the hospital. In preparation for the design we made a topographical survey of the entire 20-acre site, 6 of which encompassed the final design area. Included in this survey was locating all existing improvements including both public and private utilities serving the hospital. In addition we located two existing street rights-of-way which connected the existing site to a City street about 600 feet east of the hospital. One of these streets was constructed as part of the improvements.
A flood control pond had been constructed mostly west of the hospital site; however, the east end of the dam extended onto hospital property. This pond and dam were located as part of the survey so that storm water from the site could be discharged from a detention pond on the site to the pond behind the dam.

Intersection Improvements to Broadway: Larkin Group NM provided engineering design for a left-turn lane of Broadway Street (Business I-25) in Truth or Consequences. This project was required to facilitate ingress/egress from Broadway to a new proposed County Road Department facility. It was determined from field surveys that the existing turn lane would not accommodate large trucks utilized by County Road Department. The project was located in State right-of-way; therefore, we were required to meet NMDOT design standards in order to obtain a construction permit. Our engineers met with the County personnel to determine the dimensions of the largest truck and trailer in their fleet. Once the appropriate vehicle was identified, we designed a turn-lane median with the correct geometry to facilitate County traffic. Furthermore, the median was designed with enough vehicle queue capacity to alleviate blocking the adjacent through lane. The design included a temporary traffic control plan, paving, curb and gutter, signing, and striping.

North Side Palomas Road: This project included shoulder rehabilitation and widening, pavement resurfacing, and drainage crossing designs for just under two miles of North Side Palomas Road, County Road B070. This road has a history of accumulating silt that runs off the adjacent bluffs on one side and blows in from the nearby farmlands on the other side. The goal was to minimize the silt accumulation and provide adequate shoulder area for stockpiling debris resulting from future maintenance efforts. Also, since this stretch of CR B070 serves as a school bus route, repairing potholes and cracks and resurfacing were important in order to provide a comfortable and safe route for bus travel. Rip-rap toe walls at drainage crossings were provided to protect the pavement and adjacent shoulders from erosion. All work was done by the County Road Department. Therefore, the design used construction means and methods that were familiar to County Road Department personnel.

Monticello Road Low Water Crossing at Alamosa CreekMonticello Road Low Water Crossing at Alamosa Creek: The crossing of Alamosa Creek by Monticello Road was a dip section crossing. This has usually worked well because Alamosa Creek at this location is normally dry. However, in the wet summer of 2006, Alamosa Creek maintained a substantial flow across Monticello Road for approximately 30 consecutive days. This flow also damaged the dip pavement. The crossing was closed for about one month, cutting off convenient access to the many families living in the Alamosa Valley above it. Although the Alamosa Creek is normally dry, it has a drainage area of about 590 square miles. The construction of a bridge to pass major flows on this large stream was beyond the budget of Sierra County. Therefore, it was decided to construct a low water crossing. This crossing consists of four eight-foot by six-foot concrete box culverts with appropriate erosion control. Because the bed load of gravel is quite large in this stream, it is important that the culverts be high enough to allow a skid loader to clean the culverts after a flow.

Old Hot Springs Road: A drainage problem developed when a local farmer constructed a dike along the road to protect his newly constructed drip irrigation from sheet flooding. This change caused the flow to run down the road and flood a field about one half mile to the south. The project included raising the grade of the road and diverting water into the Garfield Drainage Ditch. Since some water still was flowing to the field to the south, a grouted rip-rap spillway was constructed at the discharge point. Additional stormwater storage was also constructed by cleaning out existing storage areas to provide more capacity.

South Side Palomas Road: This project provided for shoulder cleaning and pavement rehabilitation of approximately 1.75 miles of South Side Palomas Road. The road was still in good condition, but beginning to show cracking. The Road Department picked exactly the right time to rehabilitate this important road. In another couple of years much more work would have been required to return this road to new condition. Larkin Group NM prepared the plans and contract documents for NMDOT approval, and the Road Department personnel completed the shoulder cleaning, erosion control, and the seal coating of the road. This keeps water from penetrating the surface and provides many more years of life for this road.

Arrey Streets: This project was to construct two of the streets in this small community to County standards. However, when we surveyed the project, we found that nearly all of the right-of-way for one street was there and the existing street was within it, but the right-of-way for the other street was fragmented and much of the existing street was not in the right-of-way, sometimes not even close to it. After a public meeting, which was held on Saturday so the residents could attend, and considerable negotiation, new rights-of-way were obtained, and the new street was constructed essentially over the existing street. Because of the right-of-way problems and a rainy summer the completion of the project was delayed until September 2010.

Garfield Canal Bridge Replacement: Larkin Group NM provided design and construction phase services for the replacement of this bridge, which is situated over the Garfield Canal in Derry. The existing bridge was approximately 70 years old and in dire need of improvements. After a short study, it was determined that replacing the structure would be the cheaper option. The design was an 8'X8' concrete box culvert with wingwalls, headwalls, and apron. The total length of the structure is 75 feet. The deck width was increased to better accommodate farm equipment that frequent this road.

University Boulevard Streetscape
Client: Central New Mexico Community College (CNM)

University Boulevard Streetscape This was a safety and beautification project, located on University Boulevard SE from Basehart Road SE on the south to Coal Avenue SE on the north with a total length of approximately 1,000 feet. The project provided safety for the students crossing University Boulevard between the new 1,200-space parking lot and CNM's Main Campus.

This project included coordinating with Albuquerque's transit system study, signal design, traffic planning, and safety studies. In the project design we modified University Boulevard by removing existing left-turn holding lanes and the intermediate intersections to eliminate openings in the median. A new, continuous, landscaped median was constructed from Basehart to Coal with a five-foot-high continuous steel picket fence to discourage students from haphazardly crossing University Boulevard and directing them to cross at the lighted and signalized intersections only. The project included the installation of a new 12-foot-wide colored and textured sidewalk set back 20 feet from the curb along the west side of University. New landscaping was constructed the full length of the project within the sidewalk setback area.

Fourth Street Corridor Improvements, Phase I
Client: Village of Los Ranchos de Albuquerque

Fourth Street Corridor Improvements, Phase I This arterial street project widened approximately one half mile of Fourth Street in the Village of Los Ranchos de Albuquerque from four to five lanes with the center lane as a continuous left-turn lane broken by landscaped median islands. The intersection of Fourth and Osuna, long a bottleneck, was realigned to remove the offset across Fourth Street, and an improved signal system was installed. A signal system was also installed at Fourth Street and Schulte to provide a safer crossing for Taft Middle School students. Included in the project were a complex drainage system and replacement of all water mains in the project area.

The Taft Middle School site is being used for storm water detention under an agreement that provided for the project to build a multipurpose field and running track on the site. Much of the storm water detention volume is underground so the track and field are usable during all but the largest storms.

This project received the 2008 Project of the Year award from APWA/NM.

Isleta Boulevard - Phase 1: Roadway & Drainage Improvements
Client: Bernalillo County

Isleta Boulevard, Phase 1Larkin Group NM designed the new roadway improvements and provided the construction plans and right-of-way mapping for Isleta Boulevard, Phase 1. This old roadway has served as a major transportation route in the South Valley in Albuquerque, NM for generations. Because of Isleta Boulevard’s rich history, creation of a community-friendly environment was a top priority in the redesign of the new roadway. Project goals were two-fold: to provide a safer, more efficient roadway and to add facilities that would enhance the traditional South Valley neighborhoods. Under this project, Isleta Boulevard was widened to three lanes to provide safer left-turn access into the numerous properties along the route, and storm drainage facilities were created to handle runoff. The need for a safer roadway alignment resulted in the flattening of "Deadman’s Curve," which allowed space for a new neighborhood-friendly Urban Plaza. Additional amenities included a new multi-use park facility within a new storm water detention pond, pedestrian and bicycle facilities, roadside landscaping, artwork, and street lighting. Ultimately, these improvements will impact the quality of life for local residents and increase commerce for local businesses for the coming decades.

Larkin Group NM was honored with multiple awards for our work on Bernalillo County's Isleta Boulevard, Phase 1 project
: ACEC/NM’s 2004 Engineering Excellence Award - Small Firm Category, APWA New Mexico's 2003 Project of the Year, and Southwest Contractor Magazine's New Mexico Best of 2004 Civil / Infrastructure Project.
